'''CBX''' is a Canadian radio station, broadcasting at 740 [[Hertz|kHz]] ([[AM broadcasting|AM]]) in [[Edmonton]], [[Alberta]]. It broadcasts the programming of the [[CBC Radio One]] network. CBX is a Class B station broadcasting on a Canadian [[clear-channel]] frequency; the dominant station on 740 AM is [[CFZM]] in [[Toronto]], [[Ontario]]. CBX's studios are located at Edmonton City Centre on 102nd Avenue Northwest in [[downtown Edmonton]], while its transmitters are located near [[Beaumont, Alberta|Beaumont]].
As of Feb 28, 2021, CBX is the 3rd-most-listened-to radio station in the Edmonton market according to a PPM data report released by [[Numeris]].<ref>{{Cite web |url=https://www.radiowest.ca/forum/viewtopic.php?f=45&t=37458 |title=Winter 2021 PPM Data |access-date=2021-04-17 }}</ref>
==History==
CBX started broadcasting September 8, 1948 on a frequency of 1010 kHz.<ref>{{cite news |title=Alberta's Big Radio Station Now Open |url=https://www.newspapers.com/clip/120831138/cbx-radio-signs-on/ |access-date=March 14, 2023 |work=Red Deer Advocate |date=September 15, 1948 |page=1}}</ref> It was the third of three 50,000-watt [[Trans-Canada Network]] AM radio stations to sign on in the [[Canadian Prairie|Prairie Provinces]] (the others being [[CBK (AM)|CBK]] in [[Saskatchewan]] and [[CBW (AM)|CBW]] in [[Manitoba]]). Prior to CBX's launch, Trans-Canada Network programming aired on commercial radio stations in Edmonton, namely [[CJCA]], which continued to air CBC programming on a secondary basis after CBX signed on.<ref>{{cite news |title=City Will Get Major CBC Link |url=https://www.newspapers.com/clip/120830648/cbx-to-sign-on/ |access-date=March 14, 2023 |work=The Edmonton Bulletin |date=January 10, 1948 |page=1}}</ref>
Although CBX's initial studios were located inside the [[Hotel Macdonald]] in Edmonton, the station's transmitter was located near [[Lacombe, Alberta|Lacombe]],<ref>{{cite news |title=Powerful New Radio Station CBX Opens Here Wednesday |url=https://www.newspapers.com/clip/120830241/cbx-radio-officially-opens/ |access-date=March 14, 2023 |work=Edmonton Journal |page=6}}</ref> roughly halfway between Edmonton and [[Calgary]], in an attempt to serve the southern two-thirds of Alberta from a single transmitter.<ref>{{cite news |title=CBC To Construct New Radio Station |url=https://www.newspapers.com/clip/120831848/cbc-to-construct-separate-radio/ |access-date=March 15, 2023 |work=Edmonton Journal |date=January 31, 1963 |page=3}}</ref>
From the start, the CBX signal did not adequately cover either Edmonton or Calgary. To rectify this problem within Edmonton, a 250-watt rebroadcaster operating on 740 kHz was launched in the city in 1953. This rebroadcaster had the call sign '''CBXA'''.
Meanwhile, reception continued to be poor in Calgary.<ref>{{cite news |title=TV Sets Interfere With Radio 'Casts |url=https://www.newspapers.com/clip/120831346/cbx-reception-problems-3/ |access-date=March 14, 2023 |work=The Calgary Albertan |date=December 22, 1956 |page=3}}</ref> In order to provide a long-term solution to the station's reception issues, in 1964, the CBC launched separate radio stations for Calgary and Edmonton while also decommissioning the original CBX transmitter.<ref>{{cite news |title=CBC Move Set |url=https://www.newspapers.com/clip/120896686/cbc-to-move-lacombe-radio-transmitter/ |access-date=March 14, 2023 |work=The Calgary Albertan |date=February 4, 1964 |page=1}}</ref> Under the new setup, CBX was reoriented to be Edmonton's CBC station and took over CBXA's frequency of 740 kHz from a newly-constructed 50,000-watt transmitting site near Beaumont. At the same time, [[CBR (AM)|CBR]] signed on as Calgary's CBC outlet, using CBX's old frequency of 1010 kHz.<ref>{{cite news |title=Fifth Calgary Station Starts Broadcasting |url=https://www.newspapers.com/clip/120897231/cbr-signs-on/ |access-date=March 14, 2023 |work=Calgary Herald |date=October 1, 1964 |page=27}}</ref>
In 2004, CBC Edmonton operations moved into a new digital broadcast facility downtown, bringing all operations of Radio and TV under one roof. The old TV facility on 75th Street had {{convert|70000|sqft|m2}}, while the Radio building on 51st Ave. had {{convert|48000|sqft|m2}}. The new combined facility has 38,700 total square feet. It is located at the [[Edmonton City Centre]], on [[Churchill Square (Edmonton)|Winston Churchill Square]].
On March 16, 2006, the [[Canadian Radio-television and Telecommunications Commission]] approved the station's application to add a nested [[FM broadcasting|FM]] transmitter at 93.9 [[Hertz|MHz]] in Edmonton to simulcast the AM programming.<ref>[http://www.crtc.gc.ca/eng/archive/2006/db2006-84.htm Broadcasting Decision CRTC 2006-84]</ref> This relay, '''CBX-2-FM''', officially began April 20, 2007.
==Local programming==
[[CBC Radio One local programming|Local programs]] produced by CBX include ''Edmonton AM'', and ''Radio Active''. CBX also produces half-hourly news bulletins between 5:30 AM and 6:00 PM each weekday. Provincial or national news bulletins air on CBX outside of those hours.
CBX also produces two music shows for the entire CBC radio networks: ''[[Saturday Night Blues]]'' and ''[[Canada Live]]'' air nationally on CBC Radio One/Sirius 137 and CBC Music, respectively.

As of the spring 2009 BBM measurement, CBX is the second-most listened to radio-station in Edmonton, behind news-talk radio station [[CHED (AM)|CHED]]. ''Edmonton AM'' also ranks second in the morning, while ''Radio Active'' ranks fourth amongst the afternoon radio drive-time shows.<ref>http://www.cbc.ca/edmonton/features/cbcratings/ {{Dead link|date=February 2022}}</ref>
